Step 1: draw a number line with labeled points -1,0, and 1. Step 2: consider the denominator of the fraction to phentermine how to divide the number line : sixths.

Step 3: divide the space between integers in sixths.

Step 4: use the numerator of the fraction to count the spaces to the right of -1 and mark the point.

which best describes Devon’s first error?

A in step one Devon should have included only the numbers zero and one on the number line

B and said to Devon should have used the numerator to determine the scale

C instep three Devon should have divided the space between -1 and 1 into sixths

D and stuff for Devon should have counted five spaces to the left of zero.

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping

According to a research study, parents with young children slept 6.4 hours each night last year, on average. a random sample of 18 parents with young children was surveyed and the mean amount of time per night each parent slept was 6.8. this data has a sample standard deviation of 0.9. (assume that the scores are normally distributed.) researchers conduct a one-mean hypothesis at the 5% significance level, to test if the mean amount of time parents with young children sleep per night is greater than the mean amount of time last year. the null and alternative hypotheses are h0: μ=6.4 and ha: μ> 6.4, which is a right-tailed test. the test statistic is determined to be t0=1.89 using the partial t-table below, determine the critical value(s). if there is only one critical value, leave the second answer box blank.

The perimeter of ? cde is 55 cm. a rhombus dmfn is inscribed in this triangle so that vertices m, f, and n lie on the sides cd , ce , and de respectively. find cd and de if cf=8 cm and ef=12 cm. the answer is not cd=20 and de=15. i have tried that one, it does not work.
